Definitions

  • the selectively demetallized film can be transferred to a washing unit where any excess or remaining chemical solution can be removed.
  • the method comprises subjecting the metallized material to a flexographic printing process, wherein the inks are replaced by a metal etching solution.
  • the metal etching solution is preferably an oxidizing solution.
  • an oxidizing solution can be poured into the stainless steel ink trays of a standard flexographic printing station.
  • the oxidizing solution according to the invention preferably comprises sodium hydroxide (NaOH), water (H 2 O), and, optionally, ethylene-glycol.
  • the ethylene glycol can be used as a density-reduction agent.
  • the metallized layer of the antenna and/or the discontinuous metallized region preferably comprises at least one metal selected from the group consisting of aluminum, aluminum alloys, nickel, silver and copper.
  • the metal layer from which the antenna and/or the discontinuous metallized region is formed preferably comprises an amorphous metal.
  • An amorphous metal layer can be formed using conventional deposition techniques. By using an amorphous metal, higher conductivities can be achieved. As a result, a thinner layer can be used for the antenna, thus providing an identification device having increased flexibility.
  • the thickness of the metallized layer used to form the antenna is preferably from 0.5 to, 3 microns.
  • the use of an amorphous metal layer can also facilitate demetallization using a chemical etching solution.
  • the volume of sodium hydroxide that is "printed" on the metallized film can be controlled, as with printing using ink, by, for example, the structure (i.e., the resolution) of the printing roller (i.e., the anilox roller) and the inking rollers and by the pressure that is exerted on the printing roller.
  • the structure i.e., the resolution
  • the printing roller i.e., the anilox roller
  • the inking rollers i.e., the anilox roller
  • the resulting license plate is shown in FIG. 11 .
  • the license plate 94 comprises an antenna region 96 and a retro-reflective region 98.
  • the retro-reflective region is shown over-printed with a license plate number.
  • the retro-reflective material has been removed from the antenna region 96.
  • the antenna can be formed by selectively demetallizing a continuous metal layer using a printing procedure as described above.
